【 摘 要 】

In combined heat and power system, configuring of electric boilers, heat storage and other additional heat sources (AHS) is an effective way to alleviate the problem of wind curtailment in northeast China. In this paper, according to the currently existing peak shaving compensation mechanism, a production simulation model with AHS has been established. Based on them, the impact of AHS on the profit of combined heat and power (CHP) units, conventional (CON) units and wind farms is analyzed. Simulation system derives from a city of Jilin province, northeast of China, simulation result shows that with AHS involved, wind farms benefit most, and CHP units face profit decline. Besides, this paper also gives some advice to promote the configuration and operation of AHS, which has a guiding significance for the improvement of peak shaving compensation mechanism.
